Abstract:
PROBLEM TO BE SOLVED: To provide a method of manufacturing an electrochemical cell having a current collector which, at least partially, underlies a catalyst layer. SOLUTION: The method includes patterning a current collector 102 to have at least one electrolyte opening, disposing an electrolyte 106 into or through at least one opening, and disposing catalyst, at least in part, over the disposed electrolyte. The method includes pattering a substrate 108 and attaching a patterned current collector to each side thereof. Patterning of the current collector can include a continuous sheet, which includes a first and a second separable current collectors. In one such example, a continuous carbon-fiber sheet formed by laminating materials impregnated with a non-porous material is patterned. In another such example, a continuous plastic material sheet impregnated with one or more electrically conductive particles is patterned. The pattern of the current collector can arrange an extrusion-molded slot or adjacently-allocatable strips. COPYRIGHT: (C)2009,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a fluid storage component with high energy densities and adaptability for the unique space and size requirements of small systems such as micro fuel cell systems. SOLUTION: The method for production of the fluid storage component includes the steps of: reducing the size of active material particles sufficient to provide a maximum active material particle size substantially within the same order of size as the active material particle decrepitation size; contacting the particles with a binder sufficient to provide a mixture; compressing the mixture sufficient to provide a compacted mixture; heating the compacted mixture sufficient to form a fluid storage component; and conformably coupling an outer enclosure wall to the fluid storage component sufficient to provide a fluid enclosure.

Abstract:
PROBLEM TO BE SOLVED: To provide a chemical cell structured of discontinuous regions so that an insulation material does not give damages totally an active region of an array, since a thin-type fuel cell structure for using a micro fuel cell is provided with an electrical insulation material with some kind of an embodiment placed on the same plane with an electrode for the need to prevent electric short circuiting between adjacent cells. SOLUTION: A coating electrolyte composite material for a plurality of chemical cells making an array, includes a composite material layer, and two or more conductive regions 102, 104 arranged on a surface of the composite material. A discontinuous region 106 of an electrochemical cell member works for separating and insulating cells adjacent to each other in the array. COPYRIGHT: (C)2009,JPO&INPIT
Abstract:
Fluid coupling assemblies and methods are discussed. The fluid coupling assemblies include a first coupling member, a second coupling member magnetically engageable with the first coupling member, and a seal member disposed between a portion of the first coupling member and a portion of the second coupling member. A magnetic engagement of the first coupling member and the second coupling member unseals a fluid flow path therebetween. In certain examples, the first coupling member is sealed by a valve member and the second coupling member includes an activation member. When engaged, the valve member is moved from a closed position to an open position by the activation member, thereby unsealing the fluid flow path. A magnetic force between the first coupling member and the second coupling member can be chosen such that the members disengage when a predetermined fluid flow path pressure is reached.
